Solar Battery Performance Reduction: How to Determine If Battery Performance Is Satisfactory?

Solar Battery Performance

Solar Battery Performance Reduction – How to Determine If Battery Performance Is Satisfactory?: As your grid-connected battery ages, you may start to observe a decrease in its performance compared to its earlier days. This decline can be attributed to various factors, all of which relate to the electronic management of lithium batteries through a Battery Management System (BMS). The primary purpose of the BMS is to ensure that the batteries operate within the optimal temperature and charge range.

Consider the starting battery in your car as an example. When it’s worn out, weak, or completely discharged, it becomes evident through the struggles it faces when cranking the engine, often requiring a jump start.

On the other hand, the battery system in your house, responsible for powering appliances like the fridge, remains permanently connected to the main grid. If the battery fails to deliver the necessary power, the grid comes to the rescue. This reliance on the grid is why certain inexpensive hybrid systems with subpar surge ratings can still function, as they heavily depend on external assistance.

By closely monitoring your solar battery system, you can track the overall energy it can store. Let’s say the initial capacity is 10 kWh. When it’s new, you might observe it reaching a 100% state of charge around noon. Throughout the day, you can utilize a steady 2 kW discharge, running the air conditioning for approximately 5 hours until sundown. However, after a decade, you’ll notice that the battery takes less time to charge but provides a reduced runtime of only 3 hours in the evening.

How long is the life of a solar battery?

Solar batteries, despite their larger size, share many similarities with regular batteries. However, all batteries experience degradation as time passes. Fortunately, the lithium-ion batteries commonly employed in modern residential solar power systems tend to have a longer lifespan compared to traditional lead-acid batteries. A well-maintained and appropriately utilized lithium-ion solar battery of good quality can typically endure for approximately five to fifteen years. The actual lifespan depends on factors such as maintenance practices and frequency of usage.

When assessing the lifespan of a solar battery, it’s crucial to consider two key aspects: the battery’s “useful life” and its “warrantied life.”

Useful Life: The useful life of a solar battery is typically defined as the point at which it can only be recharged to approximately 60% of its original capacity. While the battery will still function, its efficiency will be noticeably diminished compared to its initial performance.

Warrantied Life: The warrantied life refers to the duration of the manufacturer’s guarantee for the solar battery. The specific length of the warranty varies depending on the battery model but typically falls within the range of five to fifteen years.

Most lithium-ion solar batteries have a life expectancy of at least ten years. However, it’s important to consider various factors that can influence battery lifespan, such as maintenance practices, usage patterns, environmental conditions, and the specific brand and model of the battery. These factors can impact both the useful life and the warrantied life of the solar battery.

What Factors Determines the Solar Battery Life

Understanding the factors that impact the lifespan of a solar battery is essential for optimizing its performance and longevity. Here are some important criteria to consider:

Depth of Discharge (DoD)

The lifespan of a battery is influenced by how deeply it is discharged on a regular basis. Employing shallower discharge cycles can enhance the battery’s overall longevity. It is recommended to refrain from consistently depleting the battery to its maximum capacity.


Excessive heat buildup can hasten battery degradation, whereas performance may be impacted by colder temperatures. To prevent this, it is essential to choose a well-ventilated and temperature-controlled location for battery installation.

Maintenance and Care

To extend the lifespan of the battery, it is important to perform regular maintenance tasks such as keeping it clean, inspecting connections, and monitoring its performance. It is recommended to adhere to the maintenance procedures provided by the manufacturer.

Charging and Discharging Rates

The longevity of the battery can be affected by how fast it is charged and discharged. If the battery is charged or discharged at very high rates, it can put stress on the battery and decrease its overall lifespan. It is advisable to follow the charge and discharge rates recommended by the manufacturer.

Battery Chemistry and Quality

The lifespan of a solar battery can be affected by the type and quality of battery chemistry utilized. Lithium-ion batteries are often preferred over lead-acid and other chemistries as they offer a longer lifespan. To ensure maximum longevity, it is crucial to select a trustworthy and high-quality battery brand.

Cycling Frequency

The lifespan of a battery can be influenced by the frequency at which it is charged and discharged. Batteries that undergo frequent cycles may have a shorter overall lifespan in comparison to those that have fewer cycles. By analyzing your energy usage patterns and selecting a battery size accordingly, you can optimize the frequency of charging and discharging.

Environmental Factors

The battery’s performance and lifespan can be affected by environmental factors such as humidity, direct sunlight, and air quality. To ensure the battery lasts longer, it is important to shield it from harsh environmental conditions.

When to Replace Solar Batteries?

To begin, it is recommended to conduct a thorough visual inspection of your solar battery. Pay close attention to the terminals and connections, especially if they are exposed, as these areas are prone to early signs of wear and tear. Additionally, for lead-acid batteries, it is important to check for leaks or any other visible damage. In the case of batteries nearing the end of their lifespan, you may observe bulging or bumps on the battery panel.

Apart from visual indicators of degradation, you will also notice a decrease in efficiency over time. It may take longer to fully charge, and the battery’s ability to retain power will diminish. Regularly checking the state of charge is a useful method to monitor your solar battery’s performance.

Depending on the type of solar power system you have in Perth WA, there is often a digital display available that provides comprehensive information about the battery’s condition. Alternatively, you can seek a system that includes a dedicated app for convenient monitoring and analysis of your solar battery’s performance.

Duck Curve & Its Significance for WA Households

Duck Curve & Its Significance for WA Households: Western Australia is quickly adopting solar power as a means of harnessing the abundant sunshine and embracing renewable energy. The South West Interconnected System (SWIS) has seen the installation of over 400000 residential rooftop PV systems to date. By utilizing the power of the sun, we are taking a positive step towards building a more sustainable future for both ourselves and the environment.

Despite the benefits of widespread solar adoption, it has also presented some challenges for our grid system. The reduced demand for grid electricity during daylight hours due to the use of rooftop solar by homes and businesses has placed additional strain on the grid. The resulting fluctuation in supply and demand can create instability, as illustrated by the Duck Curve. Failure to address this issue could potentially lead to blackouts in Western Australia.

What is the Duck Curve?

The Duck Curve is a term used to describe the graph that represents the fluctuation in electricity demand from the grid on days when solar energy production is high and grid demand is low. The graph typically shows a curve that resembles the shape of a duck, with distinct lines and curves.

The primary purpose of the Duck Curve graph is to highlight the potential for power system instability when the grid is faced with extreme changes in demand across different times of the day. As solar energy is exported to the grid during peak sun hours, the curves on the graph become more pronounced. 

However, as the sun sets and solar energy is no longer being generated, the graph shows a steep drop in supply, which can lead to sudden and significant demand on the grid. This can result in the energy system becoming unstable, which highlights the need for a more stable and sustainable energy solution.

The term “Duck Curve” was first used in around 2012 by the California Independent System Operator in the United States. The graph was created to illustrate the demand for electricity from a grid, with hourly solar generation and usage patterns. Since then, the Duck Curve has become a widely recognized phenomenon in the energy industry and is referenced globally as a way to understand the impact of solar power on energy grids.

Duck Curve

The graph presented above illustrates a typical Duck Curve and can be interpreted in the following manner:

The lines on the graph represent the typical amount of power dispatched by the grid over the course of a day. The large dip in the lines during the middle of the day represents when solar energy is being generated. During this time, larger generators may not be needed to meet demand.

However, as the sun sets and solar generation decreases, the lines take a steep upward curve to form the duck-like shape. This is due to the sudden increase in demand, which the grid must respond to quickly. The Duck Curve highlights the challenges faced by the energy industry in managing the fluctuating supply and demand resulting from solar power generation.

The sudden peak in demand illustrated by the steep upward curve of the Duck Curve graph can be a potential cause for system instability. In response, Future Solar WA is committed to testing initiatives that can help manage this challenge. 

As Western Australia shifts towards a renewable energy-focused future, the Duck Curve provides a valuable tool for understanding and managing the fluctuations in energy supply and demand. By exploring innovative solutions, Future Solar WA aims to ensure a stable and sustainable energy future for Western Australia.

What the Significance of Duck Curve in Perth WA

There are undoubtedly many benefits to utilizing solar power, which explains why so many Western Australian households and businesses are adopting it. Solar energy is a reliable source of power during daylight hours when the sun is shining. However, we must also consider how this adoption impacts the load and the grid.

Load refers to the demand for electricity from the grid. When solar energy output is high, demand for electricity from the grid tends to be low. This is commonly referred to as ‘low load’ and is represented by the lower line on the Duck Curve. Generally, during low load periods, people are out of their homes at work or school, so the demand for electricity is relatively low. During these periods, larger generators, such as gas or coal-fired power plants, may not be required to meet the demand for electricity and can be turned down.

As the sun sets and people return home to carry out activities such as cooking, laundry, or watching TV, almost everyone requires electricity from the grid, resulting in a spike in demand, referred to as ‘high load.’ During this period, larger generators cannot be turned up quickly enough to meet the sudden increase in demand, which could result in an unstable energy system. This is when there is a risk of a blackout occurring.

It is crucial to recognize that solar energy generation is intermittent, and although it plays a vital role in WA’s renewable energy future, it has its limitations. Cloud cover, for example, can cause solar energy output to drop rapidly, leading to potential instability in the system.

Although many households in Western Australia have installed solar panels, there is still a need for grid electricity. To help address the challenges posed by the Duck Curve, individual actions can be taken to make a difference. For instance, if you have solar panels, you can adjust your energy usage by running appliances, such as your washing machine, during the middle of the day when solar energy is abundant, in order to consume more solar energy.

Future Solar WA is working closely with the State Government and industry partners to explore innovative ways to stabilize the grid in Western Australia. We are currently conducting several exciting pilots and trials, including the testing of Virtual Power Plants (VPPs) and the Midday Saver Pilot, which is trialing a time-of-use tariff. By implementing these intelligent energy solutions, we aim to address the challenges posed by the increased use of solar power and ensure a more reliable and sustainable energy future for all.

Do Solar Panels Increase Home Value?

If you live in West Australia you will agree that we live in the sunniest state with over 3000 daylight hours on an average per year. So why not make use of this abundant source of energy?

When buying or selling a property you will look at aspects like, rates, strata fees, mortgage and even energy costs which may or may not increase based on the size of the property, your individual usage and changing circumstances. By reducing the major household cost of electricity, you can make a potential sale or rental that much more attractive.

Installing solar panels in Perth, or anywhere in Australia is a no brainer. It’s an investment that you would want to make if you want future savings as solar panels pay themselves off in the long run and provide you with affordable, clean and renewable energy for years to come.

Solar Panels effect on home value

There are studies linking solar panels to increasing home values of properties. The Appraisal Journal cited researchers Ruth Johnson and David Kaserman who report, “Home value increases of about $20 for every dollar saved on annual energy costs”. 

So for examples if you the saving after solar per month are about $200, then you could expect the value of your solar home to be worth $48,000 more than it was previously ($200 X 12 Months X 20 yrs = $48,000)

Generally, Australian believe that homes with solar are more valuable than the equivalent house without.

Based on a survey conducted by Origin Energy of 1,005 Australians aged between 18-79 from all States and Territories in 2018, it was found that 77% of Australians think a house with solar is more valuable than those relying on traditional energy sources. 

With 57% of homeowners saying they would pay up to $10,000 more for a home equipped with solar, and 60% would pay at least that much more for a home with both solar and a battery wall.

It’s not only good news for owner-occupiers , with 55% of renters saying they would be willing to pay up to $10 a week more in rent for a property with solar.

The survey also looked at the adoption of solar in Australian homes – revealing that while only 20% of people currently have solar panels installed, 57% plan to have a solar battery installed within the next 5 years.

So if you are considering installing solar panels and also contemplating a move in the next few years, do it. Not only will you start saving on your energy bills while you are still living in the house, when it comes to selling your home, you can expect your home to sell faster and also the solar installation cost to be more than recouped in full.

Return on Investment for 20kW Solar System

This article explains in detail the RoI for 20KW solar system. This will cover 20KW commercial power system cost including 20KW commercial solar panel price, 20KW commercial solar power system installation and 20KW commercial solar panel repair. Specific advantages of 20kW commercial solar panel in Perth WA will also be covered.

Most of the Australian continent receives more than 4 kWh of potential solar power per square meter per day.  When combined with the dry climate, it is an ideal location to install solar power systems

Perth WA has strong sunlight for a major part of the year. Electricity prices are on the rise which has prompted the Government to encourage solar energy installations through subsidies and incentives. Each day is a loss of opportunity. Let us go through all the factors and understand the Return on Investment for the 20kW commercial power system. Besides, for any surplus power you generate, Western Australia has a renewable energy buyback scheme.

Power Generation and Area Required by a 20kW Commercial Solar System

On average, a 20kW Solar System generates 80 to 90 kWh or kilowatt-hours per day. In normal terms, this is the unit of electricity which implies a 20kW solar system provides 80-90 units per day.

(Data Source:


Referring to this article, it shows four type of households in Australia with different appliances and consumption patterns. If we put aside household type 1 which probably is a low percentage, the others average as follows – household type 2 about 22 unitsperday, household type 3 about 14 units per day and household type4about 7 units per day. One can assess from this that an average household in Australia consumes 16-20 units per day. Hence, a small business that would have about 4 to 6 times the daily consumption is recommended a 20kW Commercial Solar System. As a business entity, one can use these parameters to ascertain their requirement. It should also be considered that such a solar system would efficiently work for around 30 years, on normal recommended maintenance.

A 20kW Solar System will require a 100 to 136 square meters area for installation. The type of panel used, angle of tilt for the sun, shade at the site, etc. can be some factors that contribute to the variation.

20KW Commercial Power System Cost

Both off-grid and on-grid systems get incentives and subsidies. On-grid systems primarily need solar panels and inverters. The mounting, racks, wiring is part of the installation which is designed based on the area available. Off-grid systems additionally require batteries for storage of energy as they are completely independent systems.

The cost of the system can be calculated as follows

1. One time installation cost:

  • 20kW commercial solar panel: the number of panels required multiplied by the price
  • Inverter
  • Racks, mounts, wiring, etc.
  • Off-grid equipment, if required
  • Labor cost for installation

2. Finance cost:

  • If financing is done from internal resources there is an opportunity cost of this capital
  • If financing options are being taken, then depending upon the option chosen the cost can be calculated

3. Maintenance cost:

  • Renewable Energy Standards lays down guidelines for maintenance. It is recommended to follow the guidelines. A well-maintained system will be more effective and last longer. It improves the Return on Investment and is money well spent.

4. Warranties:

  • Check out the warranties of the components and the obligations of the installer. Buying from a certified installer would make you eligible to get the warranties.
  • Further, there are exclusions based on weather, non-compliant installation practices, non-compliant repairs, moving the installation without the knowledge of the installer, mishandling, and breakages in transport. To overcome this, one can opt for insurance or work out a methodology when finalizing the contract with the installer.

5. Repairs:

  • Higher quality components, certified installations and maintenance practices help in getting proper customer support when required and servicing of warranties. This reduces repair costs substantially.
  • On the other hand, if a conscious decision to save some costs initially is taken, then one must be prepared to spend more on repairs and replacement to keep the system effective and long-lasting.

6. Subsidies and Incentives:

  • You should be aware of the subsidies and incentives that the Government is providing in your area.
  • Being aware is the first step to matching the information that your installer would give you.
  • These subsidies and incentives will be factored into the final cost that you would pay for the installation.

20KW Commercial Power System Savings

There are two scenarios here that one needs to understand

1. Consumption is more than the solar units generated:

  • In this case, energy from the grid is also being utilized to cover the gap.
  • The cost per unit generated by your solar system is equal to the total units generated divided by the total cost.
  • The difference in the cost per unit of the electricity purchased from the grid versus the solar cost per unit would be your saving.
  • The number of units required to equate this saving to the cost of the system will provide you the payback period or return on investment.

2. Consumption is less than the solar units generated:

  • In this case, surplus solar units are being generated that will generate some money through renewable energy buyback scheme.
  • You save on the difference between the electricity purchase unit and the solar unit generated for the solar units that you consume. You also generate some money for the surplus solar units you provide to the grid to participate in the renewable energy buyback scheme
  • Accordingly, the payback period or return on investment can be calculated.

Reference has been taken from (Data Source:www.ecogeneration.com.au) in parts to get a better understanding and build up the content of this article.


To summarize, the most important is the installation cost. You must get an authorized contractor for this. Based on warranties of each item you are procuring, your decision should consider the life of usage, the cost of maintenance and repairs. Cheaper items may have higher maintenance and repair costs proving to end up being costlier.

Another factor in your decision is the cost of financing which involves how much you can afford as a downpayment and which other options of financing are on offer.

Consider the incentives and subsidies which are likely to be discounted in the installation cost.

Finally look at the renewable energy buyback scheme and check where you stand.
